“…It seems that higher cellulose content could induce greater activity and more complex patterns of cellulase activity bands. Jatropha seed husk, with a cellulose content of only 13.52% (Department of Energy, USA), induced less intense activity bands compared to the above mentioned substrates, while rice husk and corn stubble, with cellulose content of 35-37% (Saha 2003;Liang et al 2010), induced intermediate CMCase activity.…”

“…Cellulases play a key role in industry in increasing the yield of fruit juices, beer filtration and oil extraction, improving the nutritive quality of animal feed, and enhancing the luster, smoothness, and overall quality of cellulosic garments (Liang et al 2010). In this context, it is of particular interest to study the cellulolytic activity-containing band of 25 kDa found in the B. adusta supernatants since it was produced in all substrates, shows a very clear activity and its small size could make it suitable for heterologous expression.…”

Evaluation of different lignocellulosic substrates for the production of cellulases and xylanases by the basidiomycete fungi Bjerkandera adusta and Pycnoporus sanguineus

Agricultural waste products are potential resources for the production of a number of industrial compounds, including biofuels. Basidiomycete fungi display a battery of hydrolytic enzymes with prospective use in lignocellulosic biomass transformation, however little work has been done regarding the characterization of such activities. Growth in several lignocellulosic substrates (oak and cedar sawdust, rice husk, corn stubble, wheat straw and Jatropha seed husk) and the production of cellulases and xylanases by two basidiomycete fungi: Bjerkandera adusta and Pycnoporus sanguineus were analyzed. Growth for P. sanguineus was best in rice husk while corn stubble supported the highest growth rate for B. adusta. Among the substrates tested, cedar sawdust produced the highest cellulolytic activities in both fungal species, followed by oak sawdust and wheat straw. Xylanolytic activity was best in oak and cedar sawdust for both species. We found no correlation between growth and enzyme production. Zymogram analysis of xylanases and cellulases showed that growth in different substrates produced particular combinations of protein bands with hydrolytic activity.

“…The oil cake remaining after the removal of oil, however, cannot be utilized as a fodder due its toxicity (Martínez-Herrera et al, 2006); production of additional energy from this substrate seems a reasonable solution. Several technologies may be used to achieve this: anaerobic digestion, alcohol fermentation, pyrolysis, and combustion (Liang et al, 2010;Ş en and Kar, 2011;Staubmann et al, 1997). The two latter methods offer high energy recovery, but anaerobic digestion enables the recovery of nitrogen from this material in the form of ammonium ions, which may be used as fertilizer (Batstone and Virdis, 2014).…”

“…Entretanto, devido à presença de toxinas e fatores antinutricionais ésteres de forbol, fitalatos, lectinas, inibidores de tripsina, saponinas, glicosídeos cianogênicos (MARTÍNEZ-HERRERA et al, 2006), na torta pinhão-manso, o uso dessa biomassa como ração animal é limitado, sendo necessária a utilização de tratamentos destoxificantes (KING et al, 2009). O teor de amido, apesar de menor em relação à celulose, pode ser utilizado como insumo para produção de etanol de primeira geração (LIANG et al, 2010;KUMAR et al, 2013).…”

ResumoA torta de pinhão-manso (Jatropha curcas L.), coproduto do processo de obtenção do biodiesel, apresenta um percentual significativo de carboidratos poliméricos em sua composição. Uma estratégia atraente para o aproveitamento dessa biomassa seria a biotransformação de seus carboidratos para a produção de etanol. Nesse contexto, o presente estudo teve por objetivo avaliar a composição da torta de pinhão-manso, bem como promover a otimização do processo de sacarificação enzimática da fração amilácea contida na torta e avaliar, também, a fermentabilidade do hidrolizado enzimático para produção de bioetanol. O planejamento experimental utilizado seguiu um modelo Composto Central Rotacional (CCR), cujos fatores avaliados foram o tempo de hidrólise e a concentração de enzima amilolítica, resultando em rendimento hidrolítico de 90%. O processo fermentativo realizado com Saccharomyces cerevisiae e o hidrolisado amiláceo derivado da torta de pinhão-manso apresentou valores de eficiência fermentativa de 100%. O uso da torta de pinhão-manso para produção de bioetanol pode ser uma estratégia eficiente se associada à cadeia produtiva do biodiesel como forma de agregar valor a um coproduto abundante e como alternativa para produção de uma fonte de energia renovável.Palavras-chave: biomassa; etanol; fermentação; hidrólise; Jatropha curcas L.
